Signal Private Messenger

Private messaging without the extra noise

Signal Private Messenger is a communication app for people who want ordinary messaging with stronger privacy protections. It supports text messages, voice calls, video calls, photos, files, GIFs and group conversations over an internet connection. That makes it suitable for one-to-one chats, family groups and work coordination without turning the app into a social feed.

Privacy is the main reason to use it

Messages and calls use the open-source Signal Protocol for end-to-end encryption. In practical terms, the conversation is protected so that Signal Foundation cannot read its contents. The app is run by the nonprofit Signal Foundation and does not build its service around advertising or data harvesting. A phone number is still required when registering, so Signal improves communication privacy without making users anonymous.

Useful features, kept in their place

Signal includes group chats, encrypted voice and video calls, media sharing, stickers and disappearing messages. Stories are also available for temporary updates, with controls over who can view them. The interface follows familiar messaging patterns, so moving from a standard chat app does not require learning a new system. Its feature set is practical rather than overloaded, although it offers fewer customization options than some larger messaging platforms.

A widely used privacy-focused messenger

Signal Private Messenger is published by Signal Foundation in the Communication category. It holds a rating of about 4.5 out of 5 from more than 2.8 million reviews, with 100,000,000+ installs. Those figures fit an app that people continue using for routine conversations, especially when keeping message contents away from advertisers and service operators matters.
